Answer:
4(x - 2) + x = 5x + 8
Step-by-step explanation:
In an equation with a single variable, if that variable value is any integer divided by zero then it will have infinite numbers of solutions.
<h3> Example </h3>
4(x - 2) + x = 5x + 8
To solve this, we need to rearrange like terms to the same side.
4x - 8 + x = 5x + 8
4x + x - 5x = 8 - 8
5x - 5x = 0
x(5-5) = 0
x(0) = 0
x = 0 / 0
x = ∞
Since zero is in denominator , it means that the equation has infinite number of solutions.
